PR56 Igniter Open Source
Just a note that a few months back I posted "the source" for the PR56 igniter that I've tested with GOX/kerosene.
There is a dimensioned drawing of the igniter body as well as a detailed write-up that includes parts lists and operational notes. If you make one or use it as inspiration, I'd love to hear about it via email or comment.
I'm planning on revitalizing the blog over the next few weeks, so stay tuned.

A bigger valve
Here is a larger version of an actuated valve assembly. The first version is based around a 1/4" Swagelok valve (SS-4P4T). This version mates a 3/8" SwageLok 1/4 turn plug valve (SS-6P6T or B-6P6T) to a Hitec Standard size servo.
There are two printed parts:
Shaft Coupler - http://shpws.me/r4U6
Yoke - http://shpws.me/r4kM
These are the fasteners needed:
qty 4 8-32 x 1/2"" Socket Head Cap Screw, McMaster-Carr 92196A194
qty 4 #8 Flat Washer, McMaster-Carr 96659A103
qty 2 4-40 x 1.75" Socket Head Cap Screw, McMaster-Carr 92185A128
qty 2 #4 Flat Washer, McMaster-Carr 96659A101
